Striatal prediction error modulates cortical coupling.
Both perceptual inference and motor responses are shaped by learned probabilities. For example, stimulus-induced responses in sensory cortices and preparatory activity in premotor cortex reflect how (un)expected a stimulus is. This is in accordance with predictive coding accounts of brain function, which posit a fundamental role of prediction errors for learning and adaptive behavior. We used f...
متن کاملExperimental Sleep Restriction Facilitates Pain and Electrically Induced Cortical Responses.
STUDY OBJECTIVES Sleep restriction (SR) has been hypothesized to sensitize the pain system. The current study determined whether experimental sleep restriction had an effect on experimentally induced pain and pain-elicited electroencephalographic (EEG) responses. DESIGN A paired crossover study. INTERVENTION Pain testing was performed after 2 nights of 50% SR and after 2 nights with habitua...
متن کاملDopamine prediction error responses update demand.
According to the law of demand, the quantity demanded for a reward is dependent upon the price; as the price of the reward increases, the quantity demanded decreases (1). Conversely, when the price decreases, the quantity demanded increases. This relationship can be observed at any local bar during “happy hour,” a limited time during which the price of beer is discounted. As happy hour draws to...
متن کاملDopamine Neurons Can Represent Context-Dependent Prediction Error
Midbrain dopamine (DA) neurons are thought to encode reward prediction error. Reward prediction can be improved if any relevant context is taken into account. We found that monkey DA neurons can encode a context-dependent prediction error. In the first noncontextual task, a light stimulus was randomly followed by reward, with a fixed equal probability. The response of DA neurons was positively ...
متن کاملPruning of memories by context-based prediction error.
The capacity of long-term memory is thought to be virtually unlimited. However, our memory bank may need to be pruned regularly to ensure that the information most important for behavior can be stored and accessed efficiently. Using functional magnetic resonance imaging of the human brain, we report the discovery of a context-based mechanism for determining which memories to prune. Specifically...
